Towards model-based management of database fragmentation
(
USENIX Association
, 2013 , Conference Paper)
The performance of a database can significantly deteriorate due to the fragmentation of data/index files. Manual database defragmentation and performance optimization remain time consuming and even infeasible as it requires ...
Toward a conceptual model for examining the role of social media on social customer relationship management (SCRM) system
(
Springer
, 2018 , Conference Paper)
Organizations worldwide are becoming more interested in utilizing social media applications to enhance their marketing capabilities. One of the main fruits of integrating social media applications into the marketing, ...
Urban morphology and microclimate response - Overview and case study
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
The aim of this study is to investigate the urban morphological factors that influence urban microclimate and outdoor thermal comfort in hot semi-arid climate. It explores the main features that influence the urban climate ...
A mixed space-time and wavenumber domain model for predicting ground vibration from railway tracks
(
National Technical University of Athens
, 2015 , Conference Paper)
In this paper, a mixed model for studying ground vibration generated from surface railway tracks is presented. A ballasted track with nonlinear resilient components is modelled in the time domain using the Finite Element ...
The PiP model and progress in ground vibration from railways
(
Australian Acoustical Society
, 2017 , Conference Paper)
Vibration in the ground causes problems. At large amplitude vibration causes damage, the most obvious example being earthquake damage. But the ground motion in a damaging earthquake is typically low-frequency (below 1Hz) ...
Experimental validation of a numerical model for the ground vibration from trains in tunnels
(
DC/ConfOrg
, 2015 , Conference Paper)
Ground vibration and ground-borne noise from trains in tunnels are attracting increasing attention from researchers and engineers. They are important environmental issues related with the operation of underground networks ...
Modelling the dynamic pile-soil-pile interaction in a multi-layered half-space
(
DC/ConfOrg
, 2015 , Conference Paper)
Within the context of railway ground-borne vibration, the dynamic pile-soil-pile interaction remains an area that has not been sufficiently investigated. Whilst a number of researchers have scrutinised the vibration response ...
Effect of rail unevenness correlation on the prediction of ground-borne vibration from railways
(
DC/ConfOrg
, 2015 , Conference Paper)
This paper presents the influence of rail unevenness correlation on the predicted track and ground vibration. The study is based on an integrated railway model in the wavenumber-frequency domain with varying complexity ...
Dynamic 3D imaging of gas hydrate kinetics using synchrotron computed tomography
(
EDP Sciences
, 2020 , Conference Paper)
The availability of natural gas hydrates and the continuing increase in energy demand, motivated researchers to consider gas hydrates as a future source of energy. Fundamental understanding of hydrate dissociation kinetics ...
Accounting for the influence of the free surface on the vibration response of underground railway tunnels: A new iterative method
(
KU Leuven - Departement Werktuigkunde
, 2020 , Conference Paper)
This paper presents a new method for calculating the ground-borne vibration from shallow underground railways. The method is based on an iterative wave-scattering approach, which decouples the problem into two sub-systems: ...
